Can someone please explain in simplified terms what EN1, EN2 and EN3 actually mean?
Experienced thoughts on how often each system should be trained?
For someone who swims mid-long distance freestyle, which energy systems take dominance, if any?
(clearly I'm lost!)
Thanks

From what I've read:
En1--basic endurance. Faster than warmup but slower than En2.
En2--anaerobic threshold, a pace you can determine from a timed swim (like a T-2000). Swim 2000 (or 1000) yards for time, trying to maintain an even pace. Calculate your average 100 pace to use as your threshold pace for sets.
En3--overload endurance, which will be similar to race pace. Very high intensity.
Many coaches use heart rate to guage effort. I've read that, at least for distance and middle distance swimmers, a large percentage of training should be En1, adding more En3 as the season progresses. Basic endurance sets can also be descended down to En2 or En3 pace.
